適用范圍：The purpose this part of IEC 62257-9 is to specify the general requirements for the design and the implementation of microgrids used in decentralized rural electrification to ensure the safety of persons and property and their satisfactory operation according to the scheduled use. This part of IEC 62257-9 applies to microgrids for decentralized rural electrification purposes. The microgrids covered by this part of IEC 62257-9 are low voltage a.c., three-phase or single-phase, with rated capacity less than or equal to 100 kVA. They are powered by a single micropowerplant and do not include voltage transformation. The low-voltage levels covered under this part of IEC 62257-9 are the 230 V 1-?/400 V 3-? systems, 220 V 1-?/380 V 3-?, the 120 V 1-?/208 V 3-?, 60 Hz or 50 Hz systems. This part of IEC 62257-9 specifies microgrids made of overhead lines because of technical and economical reasons in the context of decentralized rural electrification. In particular cases, underground cables can be used. The requirements cover microgrids with radial architecture.
